So, how do you explain that I play this game since few months and the issue appeared about 2 weeks ago?

I don't say that this is caused by last COD Ghost PS4 update - maybe it is caused by PS4 system update (1.62) which came in similiar time? I don't know, Activision should contact Sony and resolve this issue.

This is logically incomprehensible for me. I don't understand what could cause these drops about 2 weeks ago if the "locked 60 fps" suggestion is the clue - on the same hardware, the same COD version, only both updated about 2 weeks ago

I don't get what is so hard "incomprehensible" about it. Some people have major issues with the game while other don't. Sometimes a patch here and there screws it up for someone else and sometimes it fixes it for others. The game goes above 60fps which at that point PS4 tries to stop it since it is locked at 60fps and it causes shudders and broken frames/incomplete frames. Nothing is to hard about that to understand. IW needs to patch the game to stop it from going above the 60fps and it would stop for people.

Hi guys, This is a problem that I came across. My Tv was maxed out at 75hz, I refered to is as The Judder. and I was beginning to think I was going insane because no one else could see it. In the end I connected my PS4 to my PC monitor which can handle way more hz. Now I have crisp movement.

So at the moment the only solution I can recommend to anyone is to connect your ps4 to a decent pc monitor.

Do you guys with issues have gaming monitors? If so, maybe it needs a firmware update? My BenQ I found out today needs a firmware update. Im going to update mine today or tomorrow and ill let you know if things improve.
